Umshini we-Junda Sandblasting kanye nomshini wokuchama we-Junda yizinto ezimbili ezihlukene. Nakuba igama lifana, kunomehluko omkhulu ekusetshenzisweni. Kodwa-ke, ukuze ugweme iphutha lokukhetha komsebenzisi, kuthinte ukusetshenziswa futhi kubangele ukumosheka kwezindleko, umehluko ohambisanayo wethulwa ngokulandelayo.
1, umehluko phakathi kokudubula nokuqhunyiswa kwesihlabathi
Umgomo wokudubula nokuqhunyiswa kwe-sandblasting kuyindlela yokuhlanza ubuso bomkhiqizo usebenzisa umoya njengamandla. I-shot peening isebenzisa i-abrasive yensimbi, efana ne-steel shot, isanti yensimbi, isibhamu sobumba. Ukuqhunyiswa kwesihlabathi kusetshenziswa ama-abrasives angewona ezensimbi, njengesihlabathi se-corundum, isihlabathi sengilazi, isihlabathi se-resin nokunye.
2, uJunda udubule ukuqhuma kanye nenqubo yokuqhumisa isihlabathi
Inqubo ye-shot peening kanye ne-sandblasting isekelwe emikhiqizweni ehlukene, ukusebenza nezinye izimfuneko ukuze kunqunywe ukuthi kufanele kusetshenziswe i-shot peening noma i-sandblasting.
3. Ukukhethwa kokuqhunyiswa kwesibhamu kanye nemishini yokuqhumisa isihlabathi
I-shot peening kanye ne-sandblasting ngaphezu kwe-abrasive, abrasive recovery, idivaysi yokuhlunga e-abrasive ihlukile, ezinye izisetshenziswa zemishini ziyefana, yiqiniso, izinhlayiya ezincane ze-abrasive nazo zingaba imishini evamile kanye ne-sandblasting, vele, incike esimweni sangempela.
4. I-Shot peening kuyindlela yokukhipha ukugqwala kwensimbi ngokusebenzisa umoya ocindezelweyo noma amandla omshini we-centrifugal njengamandla kanye nokungqubuzana. Ububanzi be-projectile buphakathi kuka-0.2-2.5mm, ukucindezela komoya ocindezelwe yi-0.2-0.6mpa, kanti i-Angle phakathi kwe-jet kanye nobuso cishe ngama-degree angu-30-90. Imibhobho yenziwe ngensimbi yensimbi ye-T7 noma ye-T8 futhi iqiniswe kubunzima obungama-50-. Ukuphila kwesevisi ye-nozzle ngayinye yizinsuku ezingu-15-20. I-shot peening isetshenziselwa ukususa isikali, ukugqwala, isihlabathi esibumbayo kanye nefilimu kapende endala emikhiqizweni yensimbi ephakathi nendawo nenkulu enogqinsi olungekho ngaphansi kuka-2mm noma izingxenye zokusanhlamvu nezakhayo ezingadingi usayizi onembile kanye nekhonsathi. Kuyindlela yokuhlanza ngaphambi kokumbozwa kwendawo (i-plating). Isetshenziswa kakhulu ezindaweni ezinkulu zemikhumbi, izimboni zemishini esindayo, izimboni zezimoto nokunye. Ukwelashwa okungaphezulu ngokuchama okudutshulwa, amandla ahlabayo, umphumela wokuhlanza uyabonakala. Kodwa ukucwiliswa kwepuleti elincanyana elicutshungulwayo, kulula ukwenza i-workpiece deformation, futhi isibhamu sensimbi sishaye indawo yokusebenza (noma ngabe isibhamu siqhuma noma siyachama, ukuwohloka kwempahla yesisekelo sensimbi, ngoba akukho pulasitiki, ikhasi eliphukile, nokuwohloka kwefilimu kawoyela. ngezinto eziyisisekelo, ngakho-ke nge-workpiece kawoyela, ukuqhuma kokudubula, ukuchama kwesibhamu akukwazi ukususa ngokuphelele uwoyela.
5, i-sandblasting nayo iyindlela yokuhlanza ngomshini, kodwa i-sandblasting ayiqhumi, i-sandblasting iyisihlabathi esinjenge-quartz sand, ukuqhuma kwesibhamu kuyi-pellet yensimbi. Ezindleleni ezikhona zokwelashwa kwendawo yokusebenza, umphumela wokuhlanza wokuhlanza isihlabathi sokuqhunyiswa. I-Sandblasting ifanele ukuhlanza indawo yokusebenza enezidingo eziphakeme. Kodwa-ke, imishini yamanje yokuqhumisa isihlabathi evamile yase-China yakhiwa ikakhulukazi ihinge, i-scraper, i-lifti yebhakede kanye neminye imishini yakudala yokuthutha isihlabathi esindayo. Abasebenzisi badinga ukwakha umgodi ojulile futhi benze isendlalelo esingangenwa amanzi ukuze bafake imishini, izindleko zokwakha ziphezulu, izindleko zokunakekela nezokulungisa zinkulu. Ngokunaka kazwelonke ekuvikelweni kwemvelo kanye nempilo yezimboni, ngoba inqubo ye-sandblasting inenani elikhulu lokukhiqiza uthuli hhayi nje ukungcoliswa okukhulu kwemvelo, kodwa futhi kulula ukuholela esifweni somsebenzi we-opharetha (silicosis), inenani elikhulu ukuqhuma kwesibhamu esikhundleni se-sandblasting.
Lokhu okungenhla kumayelana nomehluko phakathi komshini wokuqhumisa isihlabathi nomshini wokudubula wokudubula, ngokwesethulo sawo, singaqonda ngokucacile ububanzi bokusebenzisa kanye nezici zemishini, ukuze sidlale kahle ukusetshenziswa kwayo, ukuhlangabezana nezidingo zokusetshenziswa. .
